Summary: The study revealed potential measurable costs of conspecific brood parasitism on the lifetime reproductive success of red-breasted mergansers, particularly limited to heavily parasitized nests.

Summary: Intraspecific brood parasitism may not be promoted by kin selection in waterfowl, as hosts spend limited time at the nest during egg laying and have constraints in parasite detection.

Summary: This study reports an event where Common Mergansers used their wings underwater to chase and capture a large fish, highlighting gaps in our understanding of avian diving physiology, hydrodynamics, and behavior.

Summary: Many animals rely on their visual systems to detect, locate or discriminate information in their environment. Visual noise caused by caustic flicker impairs the ability of fishes to detect prey, but its impacts on non-vertebrates remain untested. This study found that caustic flicker does not affect the hunting success or behavior of cuttlefish.

Summary: This study examines how foraging behavior impacts predator behavior by conducting a controlled experiment simulating hunting in captive coyotes. The results demonstrate that hunting coyotes spent more time resting and less time active, and exhibited increased boldness and persistence, but no changes in innovation. These findings highlight the potential ecological consequences of foraging behavior on predator ecology, predator-prey dynamics, and human-wildlife conflict.

Summary: This paper investigates the eco-epidemic model of predator-prey system with consideration of disease and selective behavior. The results show that the cost of fear can have destabilizing or stabilizing effects on the system, depending on the specific factors involved. The intensity of disease prevalence and the refuge taken by the prey can also impact the dynamics of the ecosystem. Additionally, the system exhibits chaotic behavior under certain conditions.

Summary: The advancement of biologging technology, such as combining GPS and accelerometry, has allowed for detailed tracking of animal behaviors, including the caching behavior of the arctic fox. The study showed a strong correlation between digging behavior and greater snow goose nesting density.

Summary: Anthropogenic lead intoxication is the main cause of death of White-tailed Sea-Eagles in Germany, largely due to ingestion of lead fragments from hunted game animals. Research findings suggest a higher presence of metal contamination in regurgitated pellets during the hunting season and in pellets containing mammalian remains.
